Final answer:
Karyohexis is not a well-defined term in modern cytology, but it appears to be related to the nuclear changes within a cell. Karyotyping is more commonly used to study chromosomes and nuclear morphology in cells undergoing processes like apoptosis or necrosis, or immune responses by leukocytes such as lymphocytes and neutrophils.
Step-by-step explanation:
Karyohexis is a term that might refer to changes observed within the nucleus of a cell. However, the provided information does not clearly define karyohexis but describes various cellular and nuclear changes related to cells undergoing stress or cell death. Potential nuclear changes include changes in cell shape from flat to round, shrinkage of the nucleus, formation of vacuoles in the cytoplasm, and complete cell lysis. These can be indicators of apoptosis or necrosis.
Moreover, leukocytes such as lymphocytes, characterized by a large nucleus and small cytoplasm, and neutrophils, which may display multi-lobed nuclei in the case of polymorphonuclear leukocytes, are integral to the immune response as part of the body's defense against infections and other abnormalities. The term karyohexis is not commonly used in modern cytology or clinical practice; rather, the detailed study of chromosomes and nuclear morphology is done through karyotyping.
